I have had the combo you are asking about for about 3 years.. all i can say is.. POWER! they are great I rarly turned up the volume knob more than 1/4 range, sounded great with truly awesome headroom and super efficent rarly get beyond a little "warm"
I recently sold/ traded mine for the W8- and 740P combo.
you should be able to pick those up for a good price i only got 6k for all three pieces. (i should have kept as I got used to all the power, now i frequently have to have the power up about 1/2 range for same volume.
Im am a sim "fanboy" now any specific questions let me know!!
good luck and enjoy whatever you get.
